Electrodes are responsible for various energy storage mechanisms in supercapacitors, while electrolytes are crucial for defining energy density, power density, cyclic stability, and efficiency of devices. Various electrolytes, from aqueous to ionic liquid, have been studied and implemented as potential electrolytes for supercapacitors.
Ionic liquid electrolytes for supercapacitors Ionic liquids are a class of molten salts that remain in a liquid state at room temperature or low temperature. They are made up of organic cations and organic or inorganic anions with significant asymmetry.
Low- tions. Ionic liquids are considered the more secure candida te as electrolytes for supercapacitors and batteries because of their low vapor pressure, high thermal stability, and non-ammability . Organic electrolyte-based supercapacitors and potential windows .
With liquid electrolytes and sufficient wetting, good utilization is almost natural . Sometimes, a few charge/discharge cycles are needed to establish full contact and wetting after the assembly of a supercapacitor . With solid electrolytes, the situation changes completely.
